For the fans however, Millar will happily and openly talk about things the studio may not want him talking about just yet. First he hinted at a Fantastic Four and X-Men crossover down the line, and now, he’s teasing what moviegoers will see in X-Men: Days of Future Past.

Director James Mangold is currently shooting The Wolverine with star Hugh Jackman, and as we speak, Jane Goldman, Simon Kinberg and Matthew Vaughn are putting together the screenplay for the series’ next installment, X-Men: Days of Future Past, which aims to redefine, and potentially relaunch the franchise.

When Bryan Singer confirmed the rumors that X-Men: First Class 2 would be indeed be based on Days of Future Past, he guardedly admitted that it would ambitiously tap into the much larger X-Men universe and blow it up, so to speak, in order to compete with the larger-scale events and crossovers we’re seeing from Marvel Studios with The Avengers and the six confirmed followup films.

In chatting with SFX magazine, Millar – who’s spending a lot of time on the set of Kick-Ass 2 – briefly discussed Matthew Vaughn’s plans for the next X-Men movie which begins shooting early next year.

“Vaughn is going for a big sci-fi style thing with X-Men: Days of Future Past.”

He described Days of Future Past as “X-Men meets The Terminator,” and continued, saying that for fans of the books, it’s “no spoiler” to reveal that the First Class sequel will explore an apocalyptic future.

For those unfamiliar with the mechanical beasts, Sentinels are giant anti-mutant killing machines. They range in size and there have been plenty of iterations of them through the years in the books, games and even the cartoons, but they’re typically purplish in color, humanoid in shape, and stand several stories tall.

If Fox, Bryan Singer and Matthew Vaughn ever wanted to up the action ante and deliver what would one of the most ambitious action set pieces seen in a comic book movie, having the X-Men (the original trilogy’s team and that of the First Class quasi-prequel) face off against an army of Sentinels would be the way to do it. Maybe Hugh Jackman can fight one solo and it’ll look like this.

And how cool would it be to see the time-travelling soldiers Cable and Bishop join the fray?
